Temperature tuning of defect state induced by the periodic cavities between the phononic crystals
The defect state in periodic structures usually leads to a pass band in the forbidden bandgap and energy localization at the position of geometric change. In this paper, we have introduced periodic cavities into a symmetric structure composing of two separated phononic crystals to construct the defe...
